1. PP Introduction
This Confidential Restricted Data, Sigmas 1 through 13 Information Group1 Protection Profile, hereafter
called CRD113PP, specifies a set of security functional and assurance requirements for the NNSA
Confidential Restricted Data, Sigmas 1 through 13 Information Group and the Information Technology
(IT) products used to create, store, process, disseminate information in this information group.
This section contains document management and overview information necessary to register the
Protection Profile (PP) in the National Nuclear Security Administration (NNSA) Protection Profile
library. The PP identification provides the labeling and descriptive information necessary to identify,
catalogue, register, and cross- reference a PP. The PP overview summarizes the profile in narrative form
and provides sufficient information for a potential user to determine whether the PP is of interest. The
overview can also be used as a standalone abstract for PP catalogues and registers. The conventions
section provides an explanation of how this document is organized and the terms section gives a basic
definition of terms that are specific to this PP.PP Identification
1.1 PP Identification
Title: NNSA Protection Profile for Confidential Restricted Data, Sigma 1 through 13 Nuclear
Weapons Information (CRD113PP)
Keywords: access control, discretionary access control, general-purpose operating system, information
protection
1.2 PP Overview
Environments, systems and products conforming to the CRD113PP support access controls that are
capable of enforcing access limitations on individual users and data objects. CRD113PP compliant
systems and products also provide an audit capability that records the security-relevant events that occur
within the system.
The CRD113PP provides for a level of protection that is appropriate for an assumed non-hostile and well-
managed user community requiring protection against threats of inadvertent or casual attempts to breach
the system security. The CRD113PP does not fully address the threats posed by malicious system
development or administrative personnel.
The CRD113PP is generally applicable to distributed systems but does not address the security
requirements that arise specifically out of the need to distribute the resources within a network.
1 Confidential Restricted Data, Sigmas 1 through 13 Nuclear Weapons -- Information that is classified as
Confidential and identified as Restricted Data or is related to nuclear weapons. This information is further identified
with at least one of the Sigma 1 through 13 categories.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
2
1.3 Strength of Environment
The strength of environment is based on the NNSA consequences of loss minimums in the NNSA PCSP
and the threats from the NNSA Cyber Risk Assessment. The assurance requirements and the minimum
strength of function were chosen to be consistent with that level of risk.
Section 7
The assurance level for CRD113PP is an NNSA AL 3, Methodically Tested and Checked, and the
minimum strength of function is SOF-medium.
1.4 Conventions
This document is organized based on Annex B of Part 1 of the Common Criteria. For each component, an
application note may appear. Application notes document guidance for how the requirement is expected
to be applied. For additional guidance, the CC itself should be consulted. Terms
This prof ile uses the following terms that are described in this section to aid in the application of the
requirements:
• User
• Authenticated User
• Administrator
• Discretionary Access Control (DAC)
Policy
• Access
• Authorization
• Category
A user is an individual who attempts to invoke a service offered by the TOE. An authenticated user is a
user who has been properly identified and authenticated. These users are considered to be legitimate users
of the TOE.
An administrator is an authenticated user who has been granted the authority to manage the TOE. These
users are expected to use this authority only in the manner prescribed by the guidance given them.
2. TOE Description
The CRD113PP defines a set of security requirements to be levied on Targets of Evaluation (TOEs)
containing the Confidential Restricted Data, Sigma 1 through 13 Nuclear Weapons Information
Information group. These TOEs include information systems that are personal electronic devices, portable
computers, and systems containing general-purpose operating systems, such as workstations, mainframes,
or personal computers. These systems can be comprised of a single host or a set of cooperating hosts in a
distributed system. Such systems permit one or more processors along with peripherals and storage
devices to be used by single or multiple users to perform a variety of functions requiring access to the
information stored on the system.
The CRD113PP is applicable to TOEs that provide facilities for on-line interaction with users, as well as
TOEs that provide for batch processing. The protection profile is also generally applicable to TOEs
incorporating network functions but contains no network specific requirements. Networking is covered
only to the extent to which the TOE can be considered to be part of a centrally managed system that meets
a common set of security requirements.
The CRD113PP assumes that responsibility for the safeguarding of the data protected by the TOEs
CRD Sigma 1 thru 13 Protection Profile Version 1.0
3
security functions (TSF) can be delegated to the TOE users. All data is under the control of the TOE. The
data are stored in objects, and the TSF can associate with each controlled object a description of the
access rights to that object.
All individual users are assigned a unique identifier. This identifier supports individual accountability.
The TSF authenticates the claimed identity of the user before allowing the user to perform any actions
that require TSF mediation, other than actions that aid an authorized user in gaining access to the TOE.
3. TOE Security Environment
3.1 Assumptions
This section describes the security aspects of the environment in which the TOE will be, or is intended to
be used. This includes information about the physical, personnel, and connectivity aspects of the
environment.
Section 8
A CRD113PP-conformant TOE is assured to provide effective security measures in a cooperative non-
hostile environment only if it is installed, managed, and used correctly. The operational environment must
be managed in accordance with assurance requirements documentation for delivery, operation, and
user/administrator guidance. The following specific conditions are assumed to exist in an environment
where CRD113PP-conformant TOEs are employed.
3.1.1 Physical Assumptions
CRD113PP-conformant TOEs are intended for application in user areas that have physical control and
monitoring. It is assumed that the following physical conditions will exist:
A.LOCATE The processing resources of the TOE will be located within
controlled access facilities that will prevent unauthorized
physical access.
A.PROTECT The TOE hardware and software critical to security policy
enforcement will be protected from unauthorized physical
modification.
3.1.2 Personnel Assumptions
It is assumed that the following personnel conditions will exist:
A.MANAGE There will be one or more competent individuals assigned to
manage the TOE and the security of the information it contains.
A.TRAINED_ADM The system administrative personnel will follow and abide by
the instructions provided by the administrator documentation.
A.COOP Users possess the necessary authorization to access at least some
of the information managed by the TOE and are expected to act
in a cooperating manner in a benign environment.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
4
3.1.3 Connectivity Assumptions
The CRD113PP contains no explicit network or distributed system requirements. However, it is assumed
that the following connectivity conditions exist:
A.PEER Any other systems with which the TOE communicates are assumed to be under the same
management control and operate under the same security policy
constraints or that the TOE is isolated by appropriate barriers,
such as controlled interfaces, firewalls, etc. CRD113PP -
conformant TOEs are applicable to networked or distributed
environments only if the entire network operates under the same
constraints and resides within a single management domain.
There are no security requirements that address connectivity to
external systems or the communications links to such systems. A
Controlled Interface may be necessary to preserve this
assumption.
A.CONNECT All connections to peripheral devices reside within the controlled
access facilities. CRD113PP-conformant TOEs only address
security concerns related to the manipulation of the TOE through
its authorized access points. Internal communication paths to
access points such as terminals are assumed to be adequately
protected.
3.2 Threats
These threats are addressed by CRD113PP compliant TOEs. The threat agents are either human users or
external IT entities not authorized to use the TOE itself. The assets that are subject to attack are the
information residing on the TOE itself.
3.2.1 TOE Threats

3.3 Organizational Security Policies
P.ACCOUNTABILITY Users are held accountable for their actions, and actions taken on
their behalf, on the information system.
P.ALT_INFRASTRUCT Information system users have, based on mission need,
continuing access to the information system hardware and
software assets.
P.AUTH_MGMT The process of generating, issuing, and using authenticators is
managed in accordance with NNSA and site policies.
Section 11
P.COMPOSITION The security of an information system or network composed of
individual information systems is equal to or greater than that of
any individual system in the combined system.
P.CONFIG_MGMT Protection features of a system are maintained during
development, modification, and maintenance of the hardware,
firmware, and software components.
P.CONOPS Continuity of operations planning is applied to applications, data,
and information systems.
P.CREDENTIAL_PROTECTION Authentication credentials shall be protected to prevent
unauthorized access, modification or destruction. This policy
requires that the individuals and IT entities that use the
CRD Sigma 1 thru 13 Protection Profile Version 1.0
10
credentials adequately protect all credentials. The information
system supports this policy by restricting access to credentia ls,
by protecting the credentials as they are transmitted over the
network during the domain authentication process, and through
the trusted path between the credential reader and other
information system components.
P.CRYPTOGRAPHY Cryptographic services that are used to ensure information
confidentiality, privacy or integrity shall meet the criteria of the
appropriate robustness (strength of mechanism and assurance)
based on the value of information to be protected and the threat
environment.
P.CTL_INTERFACE Protection requirements and adjudication of security policy
differences are enforced when two or more information systems
or networks are interconnected.
P.DATA_ASSURANCE Modification of data is permitted only by authorized personnel.
P.DATA_AVAILABILITY User and information system data are available, or restorable, to
meet mission availability requirements

5. IT Security Requirements
5.1 TOE Security Functional Requirements
This section defines the functional requirements for the TOE. Functional requirements components in this
profile were drawn from Part 2 of the CC. Some functional requirements are extensions to those found in
the CC.
CC defined operations for assignment, selection, and refinement were used to tailor the requirements to
the level of detail necessary to meet the stated security objectives. These operations are indicated through
the use of underlined (assignments and selections) and italicized (refinements) text. All required
operations not performed within this profile are clearly identified and described such that they can be
correctly performed upon instantiation of the PP into a Security Target (ST) specification.
Section 19
NOTE: Where italicized items are listed in an assignment or selection clause in one of the following
components, the ST developer must address the component and provide the information identified in the
italicized clause. If the assignment or selection clause is not italicized, the item is mandatory and must be
addressed in the ST.
5.1.1 FAU_ARP.1 Security alarms
5.1.1.1 FAU_ARP.1.1 The TSF shall take [assignment: list of the least disruptive actions] upon
detection of a potential security violation.
Application Note: The ST must state the actions taken by the TOE when a potential security
violation, such as detection of malicious code, or a successful or unsuccessful intrusion.
5.1.2 FAU_GEN.1 Audit data generation
5.1.2.1 FAU_GEN.1.1 The TSF shall be able to generate an audit record of the following
auditable events:
• Start-up and shutdown of the audit functions;
• All auditable events for the basic level of audit and the events listed
below:
o Successful use of the user security attribute administration
functions
o All attempted uses of the user security attribute administration
functions
CRD Sigma 1 thru 13 Protection Profile Version 1.0
22
o Identification of which user security attributes have been
modified
o Successful & unsuccessful logons and logoffs
o Unsuccessful access to security relevant files including creating,
opening, closing, modifying, & deleting those files
o Changes in user authenticators
o Blocking or blacklisting user Ids, terminals, or access ports
o Denial of access for excessive logon attempts
o System accesses by privileged users; a. Privileged activities at the
system console (either physical or logical consoles) and other
system- level accesses by privileged users.
o Starting and ending times for each access to the system
Application Note: For some situations it is possible that some events cannot be automatically
generated. This is usually due to the audit functions not being operational at the time these
events occur. Such events need to be documented in administrative guidance, along with
recommendations on how manual auditing should be established to cover these events.
The "basic" level of auditing was selected as best representing the "mainstream" of
contemporary audit practices used in the target environments.
5.1.2.2 FAU_GEN.1.2 The TSF shall record within each audit record at least the following
information:
a. Date and time of the event, type of event, subject identity, and the
outcome (success or failure) of the event; and
b. For each audit event type, based on the auditable event definitions of
the functional components included in the PP/ST, [assignment: other
audit relevant information]
5.1.3 FAU_GEN.2 User identity association
5.1.3.1 FAU_GEN.2.1 The TSF shall be able to associate each auditable event with the identity
of the user that caused the event.
Application Note: There are some auditable events that may not be associated with a user, such
as failed login attempts. It is acceptable that such events do not include a user identity. In the
case of failed login attempts it is also acceptable not to record the attempted identity in cases
where that attempted identity could be misdirected authentication data; for example when the
user may have been out of sync and typed a password in place of a user identifier.
5.1.4 FAU_SAA.1 Potential violation analysis
5.1.4.1 FAU_SAA.1.1 The TSF shall be able to apply a set of rules in monitoring the audited
events and based upon these rules indicate a potential violation of the
TSP.
Section 20
CRD Sigma 1 thru 13 Protection Profile Version 1.0
23
5.1.4.2 FAU_SAA.1.2 The TSF shall enforce the following rules for monitoring audited
events:
Accumulation or combination of [assignment: subset of defined
auditable events] known to indicate a potential security violation;
[assignment: any other rules].
Application Note: The ST must describe the auditable events that are known or suspected to
indicate a potential security violation.
5.1.5 FAU_SAA.2 Profile based anomaly detection
5.1.5.1 FAU_SAA.2.1 The TSF shall be able to maintain profiles of systems usage, where an
individual profile represents the historical patterns of usage performed
by the members of [assignment: the profile target group].
5.1.5.2 FAU_SAA.2.2 The TSF shall be able to maintain s suspicious rating associated with
each user whose activity is recorded in the profile, where the suspicious
rating represents the degree to which the user’s current activity is
found inconsistent with the established patterns of usage represented in
the profile.
5.1.5.3 FAU_SAA.2.3 The TSF shall be able to indicate an imminent violation of the TSP
when a user’s suspicion rating exceeds the following threshold condition
[assignment: conditions under which anomalous activity is reported by
the TSF].
5.1.6 FAU_SAA.4 Complex attack heuristics
5.1.6.1 FAU_SAA.4.1 The TSF shall be able to maintain an internal representation of the
following event sequences of known intrusion scenarios [assignment: list
of sequences of system events whose occurrence are representative of
known penetration scenarios] and the following signature events
[assignment: a subset of system events] that may indicate a potential
violation of the TSP.
Application Note: The ST must describe, or reference documentation of, known or suspected
system events and penetration scenarios that may indicate a potential security violation. The
specific manner of implementation is TOE dependent and can be achieved through the use of
intrusion detection software on the TOE or in the local area network where the TOE is located.
5.1.6.2 FAU_SAA.4.2 The TSF shall be able to compare the signature events and event
sequences against the record of sys tem activity discernible from an
examination of [assignment: the information to be used to determine
system activity].
Application Note: See application note for FAU_SAA.4.1.

Application Note: See application note for FAU_SAA.4.1.
5.1.7 FAU_SAR.1 Audit review
5.1.7.1 FAU_SAR.1.1 The TSF shall provide [assignment: Computer System Security Officers
(CSSO) and authorized system administrators] with the capability to
read [assignment: all audit information] from the audit records.
Application Note: The minimum information that must be provided is the same that which is
required to be recorded in FAU_GEN.1.2. The intent of this requirement is that there exists a
tool for an administrator to access the audit trail in order to assess it. Exactly what manner is
provided is an implementation decision, but it needs to be done in a way that allows the
administrator to make effective use of the information presented. This requirement is closely
tied to FAU_SAR.3 and FAU_SEL.1. It is expected that a single tool will exist within the TSF
that will satisfy all of these requirements.
Section 21
5.1.7.2 FAU_SAR.1.2 The TSF shall provide the audit records in a manner suitable for the
user to interpret the information.
5.1.8 FAU_SAR.2 Restricted audit review
5.1.8.1 FAU_SAR.2.1 The TSF shall prohibit all users read access to the audit records, except
those users that have been granted explicit read-access.
Application Note: By default, CSSOs and authorized system administrators may be considered
to have been granted read access to the audit records. The TSF may provide a mechanism that
allows other users to also read audit records.
5.1.9 FAU_SAR.3 Selectable audit review
5.1.9.1 FAU_SAR.3.1 The TSF shall provide the ability to perform [selection: searches,
sorting, and ordering] of audit data based on based on the following
attributes:
a. User identity;
b. [assignment: list of additional attributes that audit selectivity is
based upon]
Application Note: The ST must state the additional attributes that audit selectivity may be
based upon (e. g., object identity, type of event), if any.
5.1.10 FAU_SEL.1
5.1.10.1 FAU_SEL.1.1 The TSF shall be able to include or exclude auditable events from the
set of audited events based on the following attributes:
a. User identity;
b. [assignment: list of additional attributes that audit selectivity is based
upon].
CRD Sigma 1 thru 13 Protection Profile Version 1.0

Application Note: The ST must state the additional attributes that audit selectivity may be
based upon (e. g., object identity, type of event), if any.
5.1.11 FAU_STG.2 Guarantees of audit data availability
5.1.11.1 FAU_STG.2.1 The TSF shall protect the stored audit records from unauthorized
deletion.
5.1.11.2 FAU_STG.2.2 The TSF shall be able to [selection: prevent] modifications to the audit
records.
Application Note: On many systems, in order to reduce the performance impact of audit
generation, audit records will be temporarily buffered in memory before they are written to
disk. In these cases, it is likely that some of these records will be lost if the operation of the
TOE is interrupted by hardware or power failures. The developer needs to document what the
likely loss will be and show that it has been minimized.
5.1.11.3 FAU_STG.2.3 The TSF shall ensure that [assignment: all audit records already
written to media, i.e., not in memory buffers,] audit records will be
maintained when the following conditions occur: [selection: audit
storage exhaustion, failure, and attack].
5.1.12 FAU_STG.3 Action in case of possible audit data loss
5.1.12.1 FAU_STG.3.1 The TSF shall [assignment: generate an alarm to the CSSO or
authorized system administrator] if the audit trail exceeds [assignment:
80% of capacity].
Application Note: For this component, an "alarm" is to be interpreted as any clear indication to
the administrator that the pre-defined limit has been exceeded. The ST author must state the pre-
defined limit that triggers generation of the alarm. The limit can be stated as an absolute value,
or as a value that represents a percentage of audit trail capacity (e. g., audit trail 80% full). If the
limit is adjustable by the authorized administrator, the ST should also incorporate an FMT
requirement to manage this function.
5.1.13 FAU_STG.4 Prevention of audit data loss
5.1.13.1 FAU STG.4.1 The TSF shall [selection: be able to prevent auditable events, except
those taken by the CSSO or authorized system administrator,] and
[assignment: other actions to be taken in case of audit storage failure] if
the audit trail is full.
Section 22
Application Note: The selection of "preventing auditable actions if audit storage is exhausted"
is minimal functionality; providing a range of configurable choices (e. g., ignoring auditable
actions and/ or changing to a degraded mode) is allowable, as long as "preventing" is one of the
choices. If configurable, then FMT_ MOF.1 should be incorporated into the ST.
5.1.14 FCS_CKM.4 Cryptographic key destruction
5.1.14.1 FCS_CKM.4.1 The TSF shall destroy cryptographic keys in accordance with a
specified cryptographic key destruction method [assignment:
CRD Sigma 1 thru 13 Protection Profile Version 1.0
26
cryptographic key destruction method] that meets the following:
[assignment: list of standards].
5.1.15 FCS_COP.1 Cryptographic operation
5.1.15.1 FCS_COP.1.1 The TSF shall perform [assignment: list of cryptographic operations] in
accordance with a specified cryptographic algorithm [assignment:
cryptographic algorithm] and cryptographic key sizes [assignment:
cryptographic key sizes] that meet the following: [assignment: list of
standards].
5.1.16 FDP_ACC.2 Complete access control
5.1.16.1 FDP_ACC.2.1 The TSF shall enforce the [assignment: Discretionary Access Control
Policy (DAC)] on [assignment: list of subjects] acting on the behalf of
users, [assignment: list of named objects] and all operations among
subjects and objects covered by the SFP [DAC policy].
Application Note: For most systems there is only one type of subject, usually called a process
or task, which needs to be specified in the ST.
Named objects are those objects that are used to share information among subjects acting on
the behalf of different users and for which access to the object can be specified by a name or
other identity. Any object that meets this criterion but is not controlled by the DAC policy must
be justified.
The list of operations covers all operations between the above two lists. It may consist of a
sublist for each subject-named object pair. Each operation needs to specify which type of
access right is needed to perform the operation; for example read access or write access.
5.1.16.2 FDP_ACC.2.2 The TSF shall ensure that all operations between any subject in the
TSC and any object within the TSC are covered by an access control
SFP.
5.1.17 FDP_ACF.1 Security attribute based access control
5.1.17.1 FDP_ACF.1.1 The TSF shall enforce the [assignment: Discretionary Access Control
Policy] to objects based on [assignment: the following:]
a. The user identity and group membership(s) associated with a
subject;
b. The following access control attributes associated with an object;
and
c. [assignment: List access control attributes. The attributes must
provide permission attributes with:
a. the ability to associate allowed or denied operations with one
or more user identities;
CRD Sigma 1 thru 13 Protection Profile Version 1.0
27
b. the ability to associate allowed or denied operations with one
or more group identities; and
c. defaults for allowed or denied operations.
5.1.17.2 FDP_ACF.1.2 The TSF shall enforce the following rules to determine if an operation
among controlled subjects and controlled objects is allowed:
[assignment: a set of rules specifying the Discretionary Access Control
policy, where:
a. For each operation there shall be a rule, or rules, that use the
permission attributes where the user identity of the subject matches
a user identity specified in the access control attributes of the object;
Section 23
b. For each operation there shall be a rule, or rules, that use the
permission attributes;
c. here the group membership of the subject matches a group identity
specified in the access control attributes of the object; and
d. For each operation there shall be a rule, or rules, which use the
default permission attributes specified in the access control
attributes of the object when neither a user identity nor group
identity matches.]
Application Note: A TOE that conforms to this PP is required to implement a DAC policy, but
the rules that govern the policy may vary between TOEs; those rules need to be specified in the
ST. In completing the rule assignment above, the resulting mechanism must be able to specify
access rules that apply to at least any single user. This single user may have a special status
such as the owner of the object. The mechanism must also support specifying access to the
membership of at least any single group. Conformant implementations include self/ group/
public controls and access control lists.
A DAC policy may cover rules on accessing public objects; i.e., objects which are readable to
all authorized users, but which can only be altered by the TSF or administrators. Specification
of these rules should be covered under FDP_ACF.1.3 and FDP_ACF.1.4.
A DAC policy may include exceptions to the basic policy for access by administrators or other
forms of special authorization. These rules should be covered under FDP_ACF.1.3.
The ST must list the attributes that are used by the DAC policy for access decisions. These
attributes may include permission bits, access control lists, and object ownership.
A single set of access control attributes may be associated with multiple objects, such as all
objects stored on a single floppy disk. The association may also be indirectly bound to the
object, such as access control attributes being associated with the name of the object rather than
directly to the object itself.
5.1.17.3 FDP_ACF.1.3 The TSF shall explicitly authorize access of subjects to objects based on
the following additional rules: [assignment: rules, based on security
attributes, that explicitly authorize access of subjects to objects].
CRD Sigma 1 thru 13 Protection Profile Version 1.0
28
5.1.17.4 FDP_ACF.1.4 The TSF shall explicitly deny access of subjects to objects based on the
[assignment: rules, based on security attributes, that explicitly deny access
of subjects to objects].
5.1.18 FDP_DAU.1 Basic data authentication
5.1.18.1 FDP_DAU.1.1 The TSF shall provide a capability to generate evidence that can be
used as a guarantee of the validity of [assignment: list of objects or
information types].
5.1.18.2 FDP_DAU.1.2 The TSF shall provide [assignment: list of subjects] with the ability to
verify evidence of the validity of the indicated information.
5.1.19 FDP_IFC.1 Subset information flow control
5.1.19.1 FDP_IFC.1.1 The TSF shall enforce the [assignment: Discretionary Access Control
Policy] on [assignment: list of subjects, information, and operations that
cause controlled information to flow to and from controlled subjects
covered by the SFP].
5.1.20 FDP_IFF.1 Simple security attributes
5.1.20.1 FDP_IFF.1.1 The TSF shall enforce the [assignment: Discretionary Access Control
Policy] based on the following types of subject and information security
attributes: [assignment: the minimum number and type of security
attributes].
Section 24
5.1.20.2 FDP_IFF.1.2 The TSF shall permit an information flow between a controlled subject
and controlled information via a controlled operation if the following
rules hold: [assignment: for each operation, the security attribute-based
relationship that must hold between subject and information security
attributes].
5.1.20.3 FDP_IFF.1.3 The TSF shall enforce the [assignment: additional information flow
control SFP rules].
5.1.20.4 FDP_IFF.1.4 The TSF shall provide the following [assignment: list of additional SFP
capabilities].
5.1.20.5 FDP_IFF.1.5 The TSF shall explicitly authorize an information flow based on the
following rules: [assignment: rules, based on security attributes, that
explicitly authorize information flows].
5.1.20.6 FDP_IFF.1.6 The TSF shall explicitly deny an information flow based on the
following rules: [assignment: rules, based on security attributes, that
explicitly deny information flows].
5.1.21 FDP_ITC.1 Import of user data without security attributes
5.1.21.1 FDP_ITC.1.1 The TSF shall enforce the [assignment: Discretionary Access Control
Policy] when importing user data, controlled under the SFP, from
outside of the TSC.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
29
5.1.21.2 FDP_ITC.1.2 The TSF shall ignore any security attributes associated with the user
data when imported from outside the TSC.
5.1.21.3 FDP_ITC.1.3 The TSF shall enforce the following rules when importing user data
controlled under the SFP from outside the TSC: [assignment: additional
importation control rules].
5.1.22 FDP_RIP.2 Full residual information protection
5.1.22.1 FDP_RIP.2.1 The TSF shall ensure that any previous information content of a
resource is made unavailable upon the [selection: allocation of the
resource to] all objects.
Application Note: This requirement applies to all resources governed by or used by the TSF; it
includes resources used to data and attributes. It also includes the encrypted representation of
information.
Clearing the information content store of resources on deallocation from objects is sufficient to
satisfy this requirement, if unallocated resources will not accumulate new information until
they are allocated again.
5.1.23 FDP_SDI.2 Stored data integrity monitoring and action
5.1.23.1 FDP_SDI.2.1 The TSF shall monitor user data stored within the TSC for
[assignment: unauthorized modification and unauthorized deletion] on
all objects, based on the following attributes: [assignment: user data
attributes].
Application Note: The ST must describe the user data attributes, i.e. file names, directory
names, sizes, etc., that will be used in the detection of unauthorized activities on the data.
5.1.23.2 FDP_SDI.2.2 Upon detection of a data integrity error, the TSF shall [assignment:
enter a description of the error in the audit log and issue an alarm].
Application Note: For this component, an "alarm" is to be interpreted as any clear indication to
the administrator that a data integrity error has been detected. The ST must state the conditions
that trigger generation of the alarm.
5.1.24 FIA_AFL.1 Authentication failure handling
5.1.24.1 FIA_AFL.1.1 The TSF shall detect when [assignment: five (5) consecutive]
unsuccessful authentication attempts occur related to [assignment: list
of authentication events].
Application Note: The ST must state the authentication events that will be monitored for 5
consecutive unsuccessful authentication attempts. The ST should also identify any
authentication activities that are not monitored for unsuccessful authentication attempts.
Section 25
5.1.24.2 FIA_AFL.1.2 When the defined number of unsuccessful authentication attempts has
been met or surpassed, the TSF shall [assignment: list of actions].
CRD Sigma 1 thru 13 Protection Profile Version 1.0
30
5.1.25 FIA_ATD.1 User attribute definition
5.1.25.1 FIA_ATD.1.1 The TSF shall maintain the following list of security attributes
belonging to individual users: [assignment:
a. User Identifier;
b. Group Memberships;
c. Authentication Data;
d. Security-relevant Roles; and
e. [assignment: other user security attributes]].
Application Note: The specified attributes are those that are required by the TSF to enforce the
DAC policy, the generation of audit records, and proper identification and authentication of
users. The user identity must be uniquely associated with a single individual user.
Group membership may be expressed in a number of ways: a list per user specifying to which
groups the user belongs , a list per group which includes which users are members, or implicit
association between certain user identities and certain groups. A TOE may have two forms of
user and group identities, a text form and a numeric form. In these cases there must be unique
mapping between the representations.
5.1.26 FIA_SOS.1 Verification of secrets
5.1.26.1 FIA_ SOS.1 The TSF shall provide a mechanism to verify that secrets meet
[assignment: the P.STRONG_AUTHENTICATION policy].
Application Note: The method of authentication is unspecified by this PP, but must be
specified in a ST. The method that is used must be shown to implement the
P.STRONG_AUTHENTICATION policy. If a password mechanism is used, the mechanism
must comply with NNSA password policies. The strength of whatever mechanism
implemented must be subjected to strength of function analysis. (See AVA_SOF.1)
5.1.27 FIA_UAU.1 Timing of authentication
5.1.27.1 FIA_UAU.1.1 The TSF shall allow [assignment: list of TSF mediated actions] on behalf
of the user to be performed before the user is authe nticated.
Application Note: The ST must specify the actions that are allowed by an unauthenticated user.
The allowed actions should be limited to those things that aid an authenticated user in gaining
access to the TOE. This could include help facilities or the ability to send a message to
administrators.
5.1.27.2 FIA_UAU.1.2 The TSF shall require each user to be successfully authenticated before
allowing any other TSF-mediated actions on the behalf of that user.
5.1.28 FIA_UAU.7 Protected authentication feedback
5.1.28.1 FIA_UAU.7.1 The TSF shall provide only [assignment: obscured feedback] to the user
while the authentication is in progress.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
31
Application Note: Obscured feedback implies the TSF does not produce a visible display of
any authentication data entered by a user, such as through a keyboard (e. g., echo the password
on the terminal). It is acceptable that some indication of progress be returned instead, such as a
period returned for each character sent.
Some forms of input, such as card input based batch jobs, may contain human-readable user
passwords. The administrative and user guidance documentation must explain the risks in
placing passwords on such input and must suggest procedures to mitigate that risk.
5.1.29 FIA_UID.1 Timing of identification
5.1.29.1 FIA_UID.1.1 The TSF shall allow [assignment: list of TSF-mediated actions] on behalf
of the user to be performed before the user is identified.
Section 26
5.1.29.2 FIA_UID.1.2 The TSF shall require each user to be successfully identified before
allowing any other TSF-mediated actions on behalf of that user.
Application Note: The ST must specify the actions that are allowed to an unidentified user. The
allowed actions should be limited to those things that aid an authenticated user in gaining access
to the TOE. This could include help facilities or the ability to send messages to administrators.
The method of identification is unspecified by this PP, but should be specified in a ST and it
should specify how this relates to user identifiers maintained by the TSF.
5.1.30 FIA_USB.1 User-subject binding
5.1.30.1 FIA_USB.1.1 The TSF shall associate the appropriate user security attributes with
subjects acting on behalf of that user.
5.1.30.1.1 The TSF shall associate the following user security attributes with subjects acting on the
behalf of that user:
a. The user identity which is associated with auditable events;
b. The user identity or identities which are used to enforce the
Discretionary Access Control Policy;
c. The group membership or memberships used to enforce the
Discretionary Access Control Policy;
d. [assignment: any other user security attributes].
5.1.30.1.2 The TSF shall enforce the following rules governing changes to the user security
attributes associated with subjects acting on the behalf of a user: [assignment: changing
of attributes rules].
Application Note: The DAC policy and audit generation require that each subject acting on the
behalf of users have a user identity associated with the subject. This identity is normally the one
used at the time of identification to the system. The DAC policy enforced by the TSF may
include provisions for making access decisions based on a user identity that differs from the
one used during identification.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
32
The ST must state, in FIA_USB.1.1, how this alternate identity is associated with a subject and
justify why the individual user associated with this alternate identity is not compromised by the
mechanism used to implement it. Depending on the TSF's implementation of group
membership, the associations between a subject and groups may be explicit at the time of
identification or implicit in a relationship between user and group identifiers. The ST must
specify this association. Like user identification, an alternate group mechanism may exist, and
parallel requirements apply.
5.1.31 FMT_MOF.1 Management of security functions behavior
5.1.31.1 FMT_MOF.1.1 The TSF shall restrict the ability to [selection: determine the behavior of,
disable, enable, modify the behavior of] the functions [assignment: list
of functions] to [assignment: CSSOs and authorized system
administrators].
Application Note: The ST must state the restrictions and functions applied to the management
of TOE security functions by the CSSO and authorized system administrators.
5.1.32 FMT_MSA.1 Management of security attributes
5.1.32.1 FMT_MSA.1.1 The TSF shall enforce the [assignment: Discretionary Access Control
Policy] to restrict the ability to [selection: modify] the security
attributes [assignment: access control attributes associated with a
named object] to [assignment: the authorized users].
Section 27
Application Note: The ST must state the components of the access rights that may be modified,
and must state any restrictions that may exist for a type of authorized user and the components
of the access rights that the user is allowed to modify. The ability to modify access rights must
be restricted in that a user having access rights to a named object does not have the ability to
modify those access rights unless explicitly granted the right to do so. This restriction may be
explicit, based on the object ownership, or based on a set of object hierarchy rules.
5.1.33 FMT_MSA.2 Secure security attributes
5.1.33.1 FMT_MSA.2.1 The TSF shall ensure that only secure values are accepted for security
attributes.
5.1.34 FMT_MSA.3 Static attribute initialization
5.1.34.1 FMT_MSA.3.1 The TSF shall enforce the [assignment: Discretionary Access Control
Policy] to provide [selection: restrictive] default values for security
attributes that are used to enforce the SFP [Discretionary Access
Control Policy].
5.1.34.2 FMT_MSA.3.2 The TSF shall allow the [assignment: the authorized identified roles] to
specify alternative initial values to override the default values when an
object or information is created.
Application Note: A TOE conforming to this PP must provide protection by default for all
objects at creation time. This may be done through the enforcing of a restrictive default access
control on newly created objects or by requiring the user to explicitly specify the desired access
CRD Sigma 1 thru 13 Protection Profile Version 1.0
33
controls on the object at its creation. In either case, there shall be no window of vulnerability
through which unauthorized access may be gained to newly created objects.
5.1.35 FMT_MTD.1 Management of TSF data
5.1.35.1 FMT_MTD.1.1 The TSF shall restrict the ability to [selection: create, delete, and clear]
the [assignment: audit trail] to [assignment: CSSOs and authorized
system administrators].
Application Note: The selection of "create, delete, and clear" functions for audit trail
management reflect common management functions. These functions should be considered
generic; any other audit administration functions that are critical to the management of a
particular audit mechanism implementation should be specified in the ST.
5.1.35.1.1 The TSF shall restrict the ability to modify or observe the set of audited events to
administrators.
Application Note: The set of audited events are the subset of auditable events that will be
audited by the TSF. The term set is used loosely here and refers to the total collection of
possible ways to control which audit records get generated; this could be by type of record,
identity of user, identity of object, etc. It is an important aspect of audit that users are able to
affect which of their actions are audited, and therefore must not have control over or knowledge
of the selection of an event for auditing.
5.1.35.1.2 The TSF shall restrict the ability to initialize and modify the user security attributes,
other than authentication data, to administrators.
Application Note: This component only applies to security attributes that are used to maintain
the TSP. Other user attributes may be specified in the ST, but control of those attributes is not
within the scope of this PP.
5.1.35.1.3 The TSF shall restrict the ability to modify the authentication data to the following:
a) administrators; and
b) users authorized to modify their own authentication data
Section 28
Application Note: User authentication data refers to information that users must provide to
authenticate themselves to the TSF. Examples include passwords, personal identification
numbers, and fingerprint profiles. User authentication data does not include the user's identity.
The ST must specify the authentication mechanism that makes use of the user authentication
data to verify a user's identity. This component does not require that any user be authorized to
modify their authentication information; it only states that it is permissible. It is not necessary
that requests to modify authentication data require re-authentication of the requester's identity
at the time of the request.
5.1.36 FMT_REV.1 Revocation
5.1.36.1 FMT_REV.1.1 The TSF shall restrict the ability to revoke security attributes
associated with the [selection: users] within the TSC to [assignment: the
CSSO and authorized system administrators].
CRD Sigma 1 thru 13 Protection Profile Version 1.0
34
5.1.36.2 FMT_REV.1.2 The TSF shall enforce the rules: [assignment:
a) The immediate revocation of security-relevant authorizations; and
b) [assignment: list of other revocation rules concerning users]].
Application Note: Many security-relevant authorizations could have serious consequences if
misused, so an immediate revocation method must exist, although it need not be the usual
method (e. g., The usual method may be editing the trusted users profile, but the change doesn't
take effect until the user logs off and logs back on. The method for immediate revocation might
be to edit the trusted users profile and "force" the trusted user to log off.). The immediate
method must be specified in the ST and in administrator guidance. In a distributed environment
the developer must provide a description of how the "immediate" aspect of this requirement is
met.
5.1.36.2.1 The TSF shall restrict the ability to revoke security attributes associated with obje cts
within the TSC to users authorized to modify the security attributes by the Discretionary
Access Control policy.
5.1.36.3 FMT_REV.1.2 The TSF shall enforce the rules: [assignment:
a) The access rights associated with an object shall be enforced when
an access check is made; and
b) [assignment: list of other revocation rules concerning objects]].
Application Note: The DAC policy may include immediate revocation (e. g., Multics
immediately revokes access to segments) or delayed revocation (e. g., most UNIX systems do
not revoke access to already opened files). The DAC access rights are considered to have been
revoked when all subsequent access control decisions by the TSF use the new access control
information. It is not required that every operation on an object make an explicit access control
decision as long as a previous access control decision was made to permit that operation. It is
sufficient that the developer clearly documents in guidance documentation how revocation is
enforced.
5.1.37 FMT_SMR.2 Restrictions on security roles
5.1.37.1 FMT_SMR.2.1 The TSF shall maintain the roles: [assignment:
a) CSSO;
b) administrator;
c) users authorized by the Discretionary Access Control Policy to
modify object security attributes;
d) users authorized to modify their own authentication data; and
e) [assignment: other roles]].
Application Note: The ST must identify any other security relevant roles supported by the
TOE.
5.1.37.2 FMT_SMR.2.2 The TSF shall be able to associate users with roles.
Section 29
CRD Sigma 1 thru 13 Protection Profile Version 1.0
35
Application Note: A TOE conforming to this PP only needs to support a single administrative
role, referred to as the administrator. If a TOE implements multiple independent roles, the ST
should refine the use of the term administrators to specify which roles fulfill which
requirements.
This PP specifies a number of functions that are required of or restricted to an administrator,
but there may be additional functions that are specific to the TOE. This would include any
additional function that would undermine the proper operation of the TSF. Examples of
functions include: ability to access certain system resources like tape drives or vector
processors, ability to manipulate the printer queues, and ability to run real-time programs.
5.1.37.3 FMT_SMR.2.3 The TSF shall ensure that the conditions [assignment: conditions for the
different roles] are satisfied.
Application Note: If conditions or restrictions are applied to the different security relevant roles
supported by the TOE, the conditions or restrictions must be stated in the ST.
5.1.38 FPT_AMT.1 Abstract machine testing
5.1.38.1 FPT_AMT.1.1 The TSF shall run a suite of tests [selection: during initial start-up,
periodically during normal operation, at the request of an authorized user,
other conditions] to demonstrate the correct operation of the security
assumptions provided by the abstract machine that underlies the TSF.
Application Note: In general this component refers to the proper operation of the hardware
platform on which a TOE is running. The test suite needs to cover only aspects of the hardware
on which the TSF relies to implement required functions, including domain separation. If a
failure of some aspect of the hardware would not result in the TSF compromising the functions
it performs, then testing of that aspect is not required.
5.1.39 FPT_ITC.1 Inter-TSF confidentiality during transmission
5.1.39.1 FPT_ITC.1.1 The TSF shall protect all TSF data transmitted from the TSF to a
remote trusted IT product from unauthorized disclosure during
transmission.
Application Note: The ST must describe how the data is protected by one or more of the
following:
a. Information distributed only within an area approved for open storage of the
information;
b. National Nuclear Security Agency (NNSA)- approved encryption mechanisms
appropriate for the encryption of unclassified mandatory protection information;
c. NNSA approved Protected Transmission System; and
d. Approved courier.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
36
5.1.40 FPT_RCV.2 Automated recovery
5.1.40.1 FPT_RCV.2.1 When automated recovery from a failure or service discontinuity is not
possible, the TSF shall enter a maintenance mode where the ability to
return the TOE to a secure state is provided.
5.1.40.2 FPT_RCV.2.2 For [assignment: list of failure/ service discontinuities], the TSF shall
ensure the return of the TOE to a secure state using automated
procedures.
5.1.41 FPT_RVM.1 Reference Mediation
5.1.41.1 FPT_RVM.1.1 The TSF shall ensure that the TSP enforcement functions are invoked
and succeed before each function within the TSC is allowed to proceed.
Application Note: This element does not imply that there must be a reference monitor. Rather
this requires that the TSF validate all actions between subjects and objects that require policy
enforcement.
5.1.42 FPT_SEP.2 SFP domain separation
Section 30
5.1.42.1 FPT_SEP.2.1 The unisolated portion of the TSF shall maintain a security domain for
its own execution that protects it from interference and tampering by
untrusted subjects.
5.1.42.2 FPT_SEP.2.2 The TSF shall enforce separation between the security domains of
subjects in the TSC.
Application Note: This component does not imply a particular implementation of a TOE. The
implementation needs to exhibit properties that the code and the data upon which TSF relies
are not alterable in ways that would compromise the TSF and that observation of TSF data
would not result in failure of the TSF to perform its job. This could be done either by hardware
mechanisms or hardware architecture. Possible implementations include multi-state CPU’s that
support multiple task spaces and independent nodes within a distributed architecture. The
second element can also be met in a variety of ways also, including CPU support for separate
address spaces, separate hardware components, or entirely in software. The latter is likely in
layered application such as a graphic user interface system that maintains separate subjects.
5.1.42.3 FPT_SEP.2.3 The TSF shall maintain the part of the TSF related to [assignment:
Discretionary Access Control policy] in a security domain for their own
execution that protects them from interference and tampering by the
remainder of the TSF and by subjects untrusted with respect to those
SFPs.
5.1.43 FPT_STM.1 Reliable time stamps
5.1.43.1 FPT_STM.1.1 The TSF shall be able to provide reliable time stamps for its own use.
Application Note: The generation of audit records depends on having a correct date and time.
The ST needs to specify the degree of accuracy that must be maintained in order to maintain
useful information for audit records.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
37
5.1.44 FPT_TST.1 TSF testing
5.1.44.1 FPT_TST.1.1 The TSF shall run a suite of self-tests [selection: during initial start-up,

38
a. Clearing or overwriting display devices, making the current contents
unreadable;
b. Disabling any activity of the user’s data access/display devices other
than unlocking the session.
5.1.48.2 FTA_SSL.2.2 The TSF shall require the following events to occur prior to unlocking

the TOE.
ACM_CAP.3.5C The CM documentation shall describe the method used to uniquely identify
the configuration items.
ACM_CAP.3.6C The CM system shall uniquely identify all configuration items.
ACM_CAP.3.7C The CM shall describe how the CM system is used.

CRD Sigma 1 thru 13 Protection Profile Version 1.0
40
5.2.1.1.3 Evaluator action elements
ACM_CAP.3.1E The Evaluator shall confirm that the information provided meets all the
requirements for the content & presentation of evidence.
Application Note: This component provides three things. First it requires that the TOE is identifiable,
using such things as version and part numbers, to ensure that the proper thing is installed. Second it
requires that the pieces used to produce the TOE are identified. And third it requires that the production
of the TOE be done in a controlled manner.
5.2.1.2 ACM_SCP.1 TOE CM Coverage
5.2.1.2.1 Developer action elements
ACM_SCP.1.1D The developer shall provide CM documentation.
5.2.1.2.2 Content and presentation of evidence elements

tracks the following: The TOE implementation representation, design
documentation, test documentation, user documentation, administrator
documentation, and CM documentation.
ACM_SCP.1.2C The CM documentation shall describe how the configuration items are
tracked by the CM system
5.2.1.2.3 Evaluator action elements
ACM_SCP.1.1E The Evaluator shall confirm that the information provided meets all the
requirements for the content & presentation of evidence.
5.2.2 Delivery and Operation
5.2.2.1 ADO_DEL.1 Delivery Procedures
5.2.2.1.1 Developer action elements
ADO_DEL.1.1D The developer shall document procedures for delivery of the TOE or parts
of it to the user.
ADO_DEL.1.2D The developer shall use the delivery procedures.
5.2.2.1.2 Content and presentation of evidence elements

to maintain security when distributing versions of the TOE to the user’s site.
5.2.2.1.3 Evaluator action elements
ADO_DEL.1.1E The Evaluator shall confirm that the information provided meets all the
requirements for the content & presentation of evidence.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
41
Application Note: The delivery procedures for the TOE can vary greatly and range from a shrink-
wrapped box from a retail outlet to delivery by a field engineer. As such, there may be opportunities for
third parties to tamper with the TOE delivery process. In these cases the developer should provide proven
procedures or mechanisms to mitigate the threat.
5.2.2.2 ADO_IGS.1 Installation, generation, and startup procedures.
5.2.2.2.1 Developer action elements
Section 33
ADO_IGS.1.1D The developer shall document procedures necessary for the secure

requirements for content and presentation of evidence.
5.2.2.2.3 Evaluator action elements
ADO_IGS.11.E The evaluator shall determine that the installation, generation and startup
procedures result in a secure configuration.
Application Note: The required documentation depends on the way that the TOE is generated and
installed. For example the generation of the TOE from source code may be done at the development site,
in which case the required documentation would be considered part of the design documentation. On the
other hand, if some part of the TOE generation is done by the TOE administrator, it would be part of the
administrative guidance. Similar circumstances would apply to both installation and startup procedures.
5.2.3 Development
5.2.3.1 ADV_FSP.1 Informal functional specification
5.2.3.1.1 Developer action elements
ADV_FSP.1.1D The developer shall provide a functional specification.
5.2.3.1.2 Content and presentation of evidence elements
ADV_FSP.1.1C The functional specification shall describe the TSF and its external
interfaces using an informal style
ADV_FSP.1.2C The functional specification shall be internally consistent.

CRD Sigma 1 thru 13 Protection Profile Version 1.0
42
requirements for content and presentation of evidence.
ADV_FSP.1.2E The evaluator shall determine that the functional specification is an accurate
and complete representation of the TOE security functional requirements.
Application Note: This component requires that the design documentation includes a complete external
description of the TSF. In particular it needs to address the mechanisms that are used to meet the
functional requirements of the PP. Other areas need to be addressed to the degree that they affect the
functional requirements
5.2.3.2 ADV_HLD.2 Security enforcing high-level design.
5.2.3.2.1 Developer action elements

requirements for the content and presentation of evidence.
ADV_HLD.2.2E The evaluator shall determine that the high-level design is an accurate and
complete instantiation of the TOE security functional requirements.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
43
Application Note: This component requires that the design documentation include a breakdown of the
TSF at a very coarse grain. Both the developer and evaluator need to carefully choose how a subsystem is
defined for a particular TOE. There must be a balance between subsystems being too large that is
difficult to understand the functions of a single subsystem and subsystems that are so small that how they
fit into the system as a whole is difficult to understand. If different pieces of the TSF are maintained by
different groups of developers, that can aid in making these choices. Furthermore, it must be noted that
the presentation need only be informal. This means that the interfaces between subsystems need be
presented in general terms of how they interact, not to the level pf presenting a programming interface
specification between them.
5.2.3.3 ADV_RCR.1 Representation correspondence
5.2.3.3.1 Developer action elements
ADV_RCR.1.1D The developer shall provide an analysis of the correspondence between all

abstract TSF representation is correctly and completely refined in the less
abstract representation.
5.2.3.3.3 Evaluator action elements

requirements for the content and presentation of evidence.
Application Note: For the PP, this ensures that the functional specifications and high-level design are
consistent with each other.

ADV_SPM.1.2C The TSP model shall describe the rules and characteristics of all policies of
the TSP that can be modeled.
ADV_SPM.1.3C The TSP model shall include a rationale that demonstrates that it is
consistent and complete with respect to all policies of the TSP that can be
modeled.

CRD Sigma 1 thru 13 Protection Profile Version 1.0
44
functional specification shall show that all of the security functions in the
functional specification are consistent and complete with respect to the TSP
model.

6. PP Application Notes
The Discretionary Access Control Policy, also referred to as DAC, is the basic policy that CRD113PP
compliant systems and products enforce over users and resources. Whether a user is granted a requested
action, is determined by the TOE Security Policy (TSP) that is specified in this profile in the context of
Discretionary Access Control (DAC). The DAC policy is the set of rules used to mediate user access to
TOE protected objects and can be generally characterized as a policy which requires the TOE to allow
authorized users and authorized administrators to control access to objects based on individual user
identification. When the DAC policy rules are invoked, the TOE is said to be mediating access to TOE
protected objects. However, there may be instances when the DAC policy is not invoked meaning that
there may be objects residing in the TOE that are not protected by the TSP. In these instances the TOE is
said to not be mediating access to a set of objects even though the TOE is executing a (possibly
unauthorized) user request.
CRD Sigma 1 thru 13 Protection Profile Version 1.0
56
Section 43
The DAC policy consists of two types of rules: those that apply to the behavior of authorized users
(termed access rules) and those that apply to the behavior of authorized administrators (termed
authorization rules). If an authorized user is granted a request to operate on an object, the user is said to
have access to that object. There are numerous types of access; typical ones include read access and write
access, which allow the reading and writing of objects respectively. If an authorized administrator is
granted a requested service, the user is said to have authorization to the requested service or object. As for
access, there are numerous possible authorizations. Typical authorizations include auditor authorization
that allows an administrator to view audit records and execute audit tools and DAC override authorization
that allows an administrator to override object access controls to administer the system.
